There are detailed instructions on the page in the Taleworlds forums on how to integrate this mod with other mods. As long as you have the other mods' source files, combining them is just a matter of copying and pasting a few lines of code and then clicking build_module.bat. If you don't have the source files for the other mod, I'm afraid you're out of luck - you'll have to ask the mod-maker to add it himself.
